data. Every effort has been made to foresee varied emergency possibilities and develop appropriate
notification procedures for timely rescue and operations .However ,implementations of the emergency
Action Plan (EAP) involves many agencies ,who are required to work in a coordinated manner to reduce
the consequence s of the emergency triggered by the dam site condition .Effectiveness of the rescue and
relief operations depend on many factors of all the agencies involved in rescue and relief efforts and

Emergency Action Plan
Sapua Dam
Project ID Code: OR10MH0156
1 Purpose EAP is a formal plan that depicts the identification of emergency conditions at the dam site and
prescribes the pre-planned actions to be followed by the different agencies so as to mitigate the loss
to a manageable extent. The sudden release of huge quantity of water or dam break creates such
emergency conditions at dam as well as in the downstream areas, which requires warning,
evacuation, rescue and relief operations within minimum response time. The purpose of an EAP is
to protect lives and reduce property damage. EAP therefore prescribes the duties and
responsibilities of the Emergency Planning Manager and operating personnel and provides
designed procedures to identify unusual and unlikely condition which endangers Sapua Dam. Apart
from that, this Plan is designed to notify the appropriate public officials and downstream residents,
impending or actual dam failure, so that the area can be evacuated in a timely manner. EAP also
contains inundation maps to show the emergency management authorities the critical areas along
the river for action in case of an emergency. Therefore, the whole process includes coordination,
planning and joint exercises among the Emergency Planning Managers and local emergency
management authorities, who work together in response to dam safety emergencies.
2 Dam Description
General

as much as possible to notify area residents of the possible dangers.
5 Emergency Detection, Evaluation,and Classification
Emergency Detection
Situations
Many dam conditions can lead to emergency situations, not all of which will require the
implementations of the EAP. However, if any of them occur ,the appropriate actions must be
taken .ANNEXURE 4 of this EAP shows the most common emergency situations that may
26
emerge in Sapua Dam and appurtenances ,along with the corresponding specific actions to be
done by each of the dam’s officials. Some of these emergency situations are summarized as
follows:
Severe Storms/Inclement Weather: Although generally not in themselves threat to the dam
,severe storms and other inclement weather conditions can contribute to an existing problem
and hinder any remediation efforts .Several storms also cause the excessive release of
floodwater, and increase flow in already rain –swollen areas .
Tropical cyclones: Tropical cyclones do occur in the area, with the potential for structural damage to
the dam, possibly resulting in its failure. If a tropical cyclone has struck in the area, an inspection of
the dam for any signs of damage will be appropriate.
Earthquake: Sapua dam is located in the Seismic Zone Number III. This zone is classified as
Moderate Damage Risk Zone which is liable to MSK VII. and also 7.8 The IS code assigns zone
factor of 0.16 for Zone III.Thereafter, an earthquake is a possibility and appropriate post earth
earthquake inspections should be performed.
Sabotage: A threat to damage the dam has been made .Appropriate actions must be taken to protect
the dam.
Signs of Failure
Site engineers in coordination with the Emergency Planning Manager (Executive Engineer) are
responsible for conducting routine inspections and identifying conditions that could indicate the onset of
problems leading to a dam failure. The early identification of potentially dangerous conditions can allow
time for the implementation of the EAP. The following sections describe some of the different types of
failure which could lead to a dam failure.
Seepage Failure: Although all earthen embankments allow some minor seepage through the dam or
the foundation, excessive, uncontrolled seepage can result in piping (the movement of embankment
material in the seepage flow) and lead to failure. Piping can occur for years at a slow rate. If the piping
has progressed to a dangerous level, it will be evident by increased flow or the discharge of muddy water
(or both). At that stage, immediate action to stop the piping is needed. Fully developed piping is difficult
to control and is very likely to result in failure. A whirlpool in the reservoir is a sign of uncontrollable
piping and necessitates immediate emergency action.
Embankment or Foundation Sliding: Sliding is usually first apparent when cracks or bulges in
the embankment appear. Slides with progressive movement can cause failure of the embankment.
Structural Failure: The structural failure or collapse of any non-overflow portion of the dam,
spillway or spillway gates could result in loss of the reservoir. A structural failure of a portion of the
spillway could cause piping and possibly embankment failure.
Emergency Evaluation and Classification
This section lists the conditions and actions which may be used to classify the level of emergency
response, as a guide for the Emergency Planning Manager. Specific dam observations and
27
corresponding emergency classification levels can be found in ANNEXURE 4, along with
appropriate and recommended actions to follow in each case.
Internal Alert Condition BLUE — A "watch" condition. A problem has been detected at the dam
that requires constant monitoring. At this time, the distress condition is manageable by dam
personnel. The Emergency Planning Manager along with the support of site engineers will be
responsible for monitoring and repair as soon as possible and implementing the appropriate
Notification Flowchart. The following is a list of conditions that would initiate this condition:
Cloudy or dirty seepage or seepage with an increase in flow, boils, piping or bogs
Large sinkholes with corresponding seepage anywhere on the embankment or downstream
from the toe.
Any slide that degrades the crest of the embankment or that is progressively increasing in
size.
Cracking or movement of any concrete structure.
Exceptionally heavy rainfall in the catchment of the dam reservoir.
External Alert Condition ORANGE- This is indicative of a dam condition that is progressively
getting worse; and there is a high probability of dam failure. Although there is no immediate
danger, the dam could fail if conditions continue to deteriorate. The Emergency Planning
Manager will be responsible for initiating immediate repairs, including lowering the reservoir if
appropriate and implementing the appropriate Notification Flowchart. The following is a list of
conditions that would initiate this condition:
Large boils, increasing in size and flow rate, especially if there is flowing muddy water.
Significantly increasing seepage, especially flowing muddy water.
Slides involving a large mass of material that impairs the crest of the dam and is
continuing to move.
Sinkholes with seepage flowing muddy water.
Large cracks, movement or failure of a portion of any major concrete structure that
forms an integral part of the dam.
An increase in the reservoir level to near the top of the dam .
Near or above the 'Design Flood' inflow forecast.
External Alert Conditions RED - These are "failure" conditions. Either the dam is in immediate
danger of failing or has already failed. No time remains to implement measures to prevent
failure. Evacuate immediately. Evacuation efforts will continue until the situation is stabilized.
The Emergency Planning Manager is responsible for implementing the appropriate
Notification Flowchart. The following is a list of conditions that would initiate "imminent dam
failure" or "dam failure" conditions:
Rapidly increasing boils or the presence of new, significantly flowing boils, particularly
28
muddy ones near previously identified ones.
Rapidly increasing seepage, especially flowing muddy water
Slides involving a large mass of material or which have degraded the crest of the
embankment to a level that approaches the water surface level, or if significant
seepage is observed through the slide area.
Settlement that is predicted to degrade to the reservoir level.
Cracks that extend to the reservoir level.
Significant movement or failure of any structure that forms an integral part of the dam.
Overtopping of the earthen dam.
6 Previously Known Problem Structural Concerns: The length & level of stilling basin at the end of chute carrier is inadequate to
dissipate the energy at all observed discharges. The hydraulic jump extending beyond the stilling basin
will have scouring effect on D/S bed.
7 Preparedness
Preparedness actions are to be taken both before and following the development of emergency
conditions and should identify ways of preparing for an emergency, increasing response readiness in a
uniform and coordinated manner, and helping to reduce the effects of a dam failure. The following are
some steps that could prevent or delay failure after an emergency is first discovered.
Surveillance
Round the clock surveillance at the dam and its appurtenant (on the rim of reservoir (left & right)
will be carried out by site engineers during emergency situations. For this, the posting of special
observer of high experience and keen observation is an important requirement of EAP during
high flood period. To ensure that the whole system (including civil structures & mechanical
installations) is being maintained well up to satisfactory level, the repair maintenance must be
carried out as per requirement of O & M of Sapua Dam. In addition it must be ensured that
maintenance and upkeep of different components is carried out and will be only possible through
deployment of well procedure conversant and trained staff. The list of such persons should be
displayed on a photo frame mounting at convenient safe places at dam site and list of local
telephone numbers inside the dam & outside the dam area. It will be updated from time to time
for any change.
Response during weekends and holidays
The Standard Operating Procedure with Operation & Maintenance Manual is strictly followed
throughout the year whether it is weekends/holidays/night. Executive Engineer will be available
for emergency response during weekends and holidays and can be present at the dam site within
15 minutes of detection of an emergency condition. In case of non-availability of the Executive
Engineer, the Assistant Executive Engineer or Deputy Executive Engineer will take his
responsibilities.
29
Response during periods of darkness and adverse weather
The Emergency Planning Manager (Executive Engineer )and Site Engineers will arrange for access
to generators and lights to adequately monitor the situation. Site Engineers will ensure the generators
and emergency light are well maintained and available under any circumstances. Executive Engineer
will be able to access the site during adverse weather conditions by off road vehicle.
Access to the site.
The following access to the dam are available, and depending of the emergency situation some of them
should be used with caution or totally avoided (See Table 4 and ANNEXURE 1. Vicinity Map)

Remedial Actions
Preparedness and remedial actions can be taken in an emergency to prevent the catastrophic failure of
the dam, but such repairs should be undertaken with extreme caution. The repairs are only temporary,
and a permanent repair should be designed by an engineer as soon as possible.
Specific actions for different emergency situations are described in the ANNEXURE 4 (Action Data
Sheets). Examples of the actions to be taken for dam's officials under the direction of a professional
engineer or contractor are described below. In all cases, the appropriate Notification Flowchart must
be implemented and the personnel of the Odisha Dam Safety Organization be notified.
Consider the following remedial actions if the dam's integrity is threatened by:
Seepage Failure
Plug the flow with whatever material is available (clay, bentonite, or plastic) if the entrance is
in the reservoir.
Consider lower the water level in the reservoir.
Place an inverted filter (a protective layer of sand and gravel) on the exit area to hold the
material in place.
Continue operating at a lower level until a repair is made.
Embankment or Foundation Sliding
Lower the water level in the reservoir to an elevation considered safe, given the slide
30
condition.
Stabilize the slide, if on the downstream slope, by weighting the toe area below the slide with
soil, rock, or gravel.
Continue operating at a lower level until a repair is made.
Structural Failure
Implement temporary measures to protect the damaged structure, such as placing rock riprap
in the damaged area.
Lower the water level to a safe elevation through the low flow outlet.
8 Supplies and Resources
Contracts
If Sapua Project's personnel and resources prove to be inadequate during an emergency, requests will
be made for assistance from other local jurisdictions, other agencies, and industry, as needed. Such
assistance may include equipment, supplies, or personnel. All agreements will be entered into by the
following authorized officials, as deemed necessary to prevent the failure of the dam:
Emergency Planning Manager (Executive Engineer,Angul Irrigation )
Superintending Engineer, Angul Irrigation Circle,Angul
Chief Engineer & Basin Manager, Brahmani Basin ,Samal.
Equipment and Supplies
Equipment that is available for use and local contractors that can be contacted to provide
equipment during an emergency event are listed in ANNEXURE 5.
Reports
Pre-monsoon and post-monsoon inspections of the dam are made every year during the month of May
and December respectively by the Site Engineers in coordination with the Emergency Planning
Manager to evaluate its structural safety, stability, and operational adequacy. In the event of an
abnormal occurrence, reference to these reports, particularly the photographs, can be beneficial in the
evaluation of a potential problem.
Technical records such as drawings and inspection reports are stored and carefully maintained at the
Control Room in dam site and in the Emergency Planning Manager's Office. Site Engineers are
familiar with the location of the documents in the event of an emergency situation.
9 Emergency Operations Centre
Activity log
Any unusual or emergency condition should be documented, including the following:
31
Activation or deactivation of emergency facilities
Emergency notifications to other local governments and to state and central government agencies
Significant changes in the emergency
Major commitments of resources or requests for additional resources from external sources
Telephone calls will be recorded in chronological order
Issuance of protective action recommendations to the public
Evacuations and casualties
Termination of the incident
Costs of the Emergency Operations Centre
For major emergencies, the emergency operations centre will maintain detailed records of costs
expended. These records may be used to recover costs from the responsible party or insurers, or
as a basis for requesting financial assistance for certain allowable response and recovery costs
from the state or central government. Documented costs should include:
Personal cost
Equipment operation
Equipment leasing and rental
Contract services to support emergency operation
Specialized supplies expended in emergency operations
10 Inundation Area
Inundation maps in ANNEXURE 2 illustrate the areas subject to flooding from a failure of the
dam.The maps were prepared using the results of a two-dimensional flow analysis and contain
profiles of the peak flood levels expected, as well as an estimation of the time from the beginning of
the breach to the moment the location start to be inundated. More hazard reference values such as
depth, velocity and water surface elevation are included in ANNEXURE 2 in both, tabular and map
format for each of the affected locations
The bridges under inundated areas are summarized in the ANNEXURE 3 and are labelled in the
Evacuation Planning Map.
In addition to the above, Submerged roads are shown in Annexure- 1(Vicinity Map) would be .
The potential consequences either due to a hypothetical breach scenario of Sapua Dam or due to flood
higher than inflow design flood which results in high lift above the spillway.
Local Evacuation Plan
If imminent failure of Sapua Dam with uncontrolled downstream flooding is anticipated, local disaster
management and law enforcement personnel should notify those downstream, for evacuation in the most
expedient manner possible following the procedure given in the notification flow charts of this document
(Notification Flow Chart Tab). Local law enforcement officials, along with local mobile network
32
operators, radio and media representatives can best spread the notice for evacuation (See
Responsibilities Sections)
Police Departments will barricade all bridges and roads that could possibly be flooded to prevent
access to the affected area. These bridges affected are shown in the ANNEXURE 3 .Inundation Maps
along with Flood Hazard Reference Values in crossings locations included in this annexure indicate the
appropriate barricade locations under the responsibility of local law-enforcement authorities.
The Districts Disaster Management Authority (Districts Collector) will assist with the notification of all
persons and agencies involved (relief authorities), with the possibility of additional support-including
contacting others not accessible by radio or telephone.
Relief Authorities (Police, Fire Department) are generally familiar with developed areas in their jurisdiction.
Such knowledge, coupled with the requirements of state law that they respond to disasters, make them the
logical officials to be notified and to spread the warning message to all areas subject to flooding.
Based on the specific results of the dam breach analysis, a local evacuation plan has been
developed to assist disaster management authorities in the relief actions. The local evacuation plan
can be found in the ANNEXURE 3 of this EAP,
11 Implementation
Development
This EAP version has been prepared by Odisha Water Resources Department in collaboration with
Central Project Management Unit. CPMU, Disaster management authority and other agency will also
review the document and their comments will be incorporated.
Updating
The EAP should be reviewed and updated at annually or more frequently as necessary in order to assess
its workability and efficiency and to plan for improvements of the weak area.
The reviews should emphasis on the following:
Validation of contact information of personnel, mentioned in Notification flow chart. The Dam coordinator
will call all contacts within the flowcharts in the EAP to verify that phone numbers and persons in the
specified positions are current. The EAP will be revised if any of the contacts have changed.
The Superintending Engineer will organize every year prior to monsoon an orientation meeting to
introduce the revised EAP to local officials, emergency responders. This meeting will give an opportunity
to all the stakeholders to review and comment on EAP document and their respective roles.
The Emergency Planning Manager will review and complete all items on the Annual EAP Evaluation
Checklist in Annexure 8. After the annual update is complete, a new Approval and Implementation
sheet will be attached and the annual update will be documented on the Plan Review and Update sheet
in ANNEXURE 9.
33
If revisions to the EAP are made as a result of the annual update, such changes will be recorded on the
Log Sheet of Changes form at the front of the report. A copy of the updated portions of the EAP will be
sent to all concerned as per the EAP Distribution List. If the EAP was reviewed and revisions were not
required, the Dam Operator will submit written notification to all concerned that no updates to the EAP
have been adopted or implemented.
Training &Testing:
Training The training of the personnel, involved in implementation of the EAP will be conducted by the Dam
Coordinator once in a year so as to make familiar among the implementing staffs with the elements of the
plan, their responsibilities and duties, the available equipment, detection of problem and remedial
measures.
A sufficient number of people will be trained to ensure adequate coverage at all the time.
Testing: The Dam Coordinator shall organize following exercises.
1. Orientation
2. Tabletop Exercises
1. Orientation: The coordinator will regularly carry out orientation meeting with local responders and
stakeholders to solicit input, established roles during emergency situation and facilitate reliable responses
to the emergencies. In orientation meeting, the dam coordinator will introduce the revised EAP to local
officials and emergency responders and provide those entities the opportunity to review and comment on
the documents and on their roles and responsibilities, described in EAP.
2. Tabletop exercises: The Dam Coordinator and Emergency Planning Manger will organize a
tabletop drill once in 2years to discuss and review the simulated or imaginary emergency situation. The
tabletop drill involves a meeting of Emergency Planning Manager with local and state Disaster
Management Officials in a conference room. The drill begins with a description of a simulated event and
proceeds with discussions by the participants to evaluate the EAP and response procedures, and to
resolve concerns regarding coordination and responsibilities. Any problems identified during a drill should
be included in revisions to the EAP.
Before the tabletop exercise begins, meeting participants will visit the dam to familiarize with the dam site.
Emergency Planning Manager will present a scenario of an unusual or emergency event at the dam.
The scenario will be developed prior to the exercise with the support of the Dam Safety Organizations.
Once the scenario has been presented, the participants will discuss the risk involved, responses and
related actions that they would take to address and resolve the scenario throughout the exercise. The
exercise provides an opportunity to discuss EAP and response procedures and resolve the questions
throughout the exercise. It will also clarify roles and responsibilities and will identify additional threat
mitigation and preparedness actions.
34
Records and reporting of the main conclusions /findings of both meetings will be maintained in
Annexure 10 and following the deadline given in below Table
